Hey there!
The standard structure for an EngLang essay is an introduction, 3 body paragraphs and a conclusion. The classic TEEL method is a great way to structure your body paragraphs (and is where you should use your examples and quotes). A good starting point may be to look back over some past essays from old VCAA examiner's reports and see how they were constructed.
Everyone approaches essays differently, but I like to target a few topics in particular (e.g. identity, Australian English, taboo) and memorise as many recent examples and quotes about these topics. Finding complexity and conflict within a topic is a great way to add depth to your analysis.
And a great place to start finding recent examples would be this board (

Hope this answers some of your questions
Best of luck!
